• Operation Description
When M0 is turned on, the TRACE instruction is executed one time. When the TRACE instruction is executed, the data of D0
through D5 and D10 in the previous 17 scans is output to a CSV file on the SD memory card as decimal values along with the
date and time of the execution.
The saved location of CSV files is FCDATA01\TRACE\RESULT. The oldest data is saved at the top of the trace data, and the latest
data is saved at the bottom of the trace data.
When the execution of the TRACE instruction completes, the completion output M100 is turned on and the CMP instruction is
executed once. The CMP instruction compares the status code stored in the execution status D100 with 0 and turns Q0 on or off.
Q0 is turned on when an error occurs in the TRACE instruction.
